Cloudguard LoadBalancer question

[Gongya_Yu]

Almost all the videos from Youtube discuss the cloudguard deployment with load balancers.  Deep-dive Workshop: CloudGuard Network Security on Azure (Canada) explains why load balancers is used.

From Marketplace, I came  across a few different versions recently

1. there is an option to enable LB  (unfortunately I did not screenshot it) 

2. option for LB floating IP only

3. no option at all  LB.

All the templates will deploy a LB by default automatically ?

Option 3  (this is the latest version I saw) deploys a LB ?

Cluster failover via API or LB are selective ?

thanks !!

Hi, 

The High Availability  template deploy External and Internal NLB.

If you are not using Ingress , you can safely delete the external load balancer post deployment.

For the VMSS , you have the option to select in the template, if you want to deploy  External or Internal or Both.

I watched your multiple videos. thanks !!
The deployment forms above related to LB are different, any reasons ?
Ingress you referred to is Northbound ? ( we do not use it)
Southbound has to use LB ? if yes. Can we still fail over via API instead of LB ?

thanks !!!

Cluster Failover always depends on which features / traffic flows you are using. Some are relying on API calls (e.g. for movement of Public IP addresses) and some on LB Healthprobes or both. But those are not selective.

We only use southbound, the deployment template always deploys LB, right ? if yes, the UDR should point to LB, not the active node, or can we selectively point to either active node or LB ?

thanks !!

The route should always point to the LB IP. Can be found as well in the Deployment guide:

And yes the LB is always deployed as @Shay_Levin already stated. If not needed, you can also delete the Ingress LB.
